ATTACHMENT FOR BUTTON-HOLE SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 244,254, dated July 12,1881.

Application filed December 10, 1880. (No model.)

To all 'whom it may concern:

Be it known that I, JACOB KA'IZENBERG, of the city, county, and State ofNew York, have invented a new and useful Improvement in Attachments forButton-Hole-Making and Embroidering Sewing-Machines, of which thefollowing is a full, clear, and exact descrip- Tion.

Figure 1 is a perspective view of a buttonhole presser-foot to which theimprovement has been applied. Fig. 2 is a plan view, illustrating theuse of the improvement. Fig. 3 is an end elevation of the foot. Fig. 4is a crosssection of a button-hole made with and of one made without theimprovement.

Similar letters of reference indicate corresponding parts.

The object of my invention is to provide an attachment for button-holeand embroidery sewing-machines for use in laying cords along the edgesof button-holes for the purpose of filling out or raising the stitchesthat surround the same, and thus producing more finished and durablework.

The invention consists in constructing a presser-shoe with apertures forreceiving the cords and holding the same while a button- -hole is beingstitched, as hereinafter described.

A represents an ordinary presser-shoe used in making button-holes, andwhich has teeth in its lower edges to engage with and keep the foot inplace upon the work. The shoe A is pivoted to and carried by the presserarm or plate B in the ordinary manner. In the end of the shoe A areformed two holes, 0, to receive two cords, D, as shown in Fig. 2, whichcords extend longitudinally through the shoe A along the opposite sidesof the place where the button-hole is to be formed, and are held inplace by the teeth at the other end of shoe 40 A. The cords are heldtaut by the weight of the balls or of the spools, upon which the saidcords are wound and which hang from the end of the shoe. The button-holeis then worked in the ordinary manner, the stitches passing around oneof the cords in forming one side of the button-hole and around the othercord in forming the other side of the button-hole.

In some cases instead of the cords D a narrow tape may be used, and thestitches formedaround the edges of the said tape, the buttonhole beingcut through the tape and the material at the same time. In this case theapertures C are made in the form of a short slot, 0, as shown at one endof the shoe A.

I am aware that cord-guideshave been provided for use in formingbutton-holes, and that they have constituted attachments of presserfeet,as illustrated in Patent N 0. 225,523; and also, that sewing-machineprcsser-feet have been constructed withslits to serve as guides for usein stitching stay pieces or strips over uniting seams of boots or shoes.Such inventions I disclaim.

Cords or tapes of varying thickness may be employed, according as it isdesired to raise or fill out the button-hole stitches more or less.

What I claim is-- The rectangular oblong presser-shoe A, for use institching button-holes, the same having apertures in its oppositetransverse vertical end portions to receive and hold cords parallelalongside a button-hole, as specified.

JACOB KATZENBERG.
